Introduction: Graph Linear Inequalities
What you'll learn to do: graph linear inequalities on the coordinate plane
Did you know that you also use linear equations when you shop online? When you use the option to view items within a specific price range, you are asking the search engine to use a linear inequality based on price. Essentially, you are saying "show me all the items for sale between $50 and $100," which can be written as [latex]{50}\le {x} \le {100}[/latex], where x is price. In this section, you will apply what you know about graphing linear equations to graphing linear inequalities. The specific things you'll learn in this section include:- Use proper notation to graph solutions to linear inequalities
- Identify and follow steps for graphing a linear inequality in two variables
- Identify whether an ordered pair is a solution to an inequality
